    Sending Temperature and CapSense using a Custom Event

    cy2392_1568091

      I'm sending temperature data using DieTemp over a Custom Event bluetooth connection. I have generated the same process for sending CapSense proximity data but it seems that when I click "Notify" on the CySmart mobile app I am only able to see the temperature data. Is there a sequencing issue? Is the stack busy sending temperature data?

          Hi,

             

          In your BLE Component settings -> Profile -> Plant -> Temperature, set the type as uint8[] instead of uint8.

             

          Also, set the length as 2 instead of 1.

             

          Regards,

            Hello, I have a similar problem. I have a service with two characteristics ( temperature and humidity) and I created an android application to receive data from the characteristics, but I can not get one of them .

               

             

               

            This is the feature that if it works (temperature):

               


            cbtemp.setOnClickListener(new View.OnClickListener() { //CheckBox temperature

               

            @Override

               

            public void onClick(View view) {

               

            boolean isChecked = ((CheckBox) view).isChecked();

               

            if (isChecked) {

              BluetoothGattService mCustomService=mBluetoothLeService.getServices();

               

              BluetoothGattCharacteristic mCustomCharacteristic = mCustomService.getCharacteristic(UUID.fromString("00000002-0000-1000-   8000-00805f9b34fb"));   //UUID characteristic temperature

               

              final int charaProp = mCustomCharacteristic.getProperties();

               

              if ((charaProp | BluetoothGattCharacteristic.PROPERTY_READ) > 0) {

               

                if (mNotifyCharacteristic != null) {

               

                  mBluetoothLeService.setCharacteristicNotification(mNotifyCharacteristic, false);

               

                  mNotifyCharacteristic = null;

               

                  }

               

            mBluetoothLeService.readCharacteristic(mCustomCharacteristic); }

               

            if ((charaProp | BluetoothGattCharacteristic.PROPERTY_NOTIFY) > 0) {

               

                mNotifyCharacteristic = mCustomCharacteristic;

               

                mBluetoothLeService.setCharacteristicNotification(mCustomCharacteristic, true); }

            }

               

            });

            where getservices() function is :

            public BluetoothGattService getServices(){

               

            return mBluetoothGatt.getService(UUID.fromString("00000001-0000-1000-8000-00805f9b34fb"));  //UUID Service

               

            }

               


            For the characteristic humidity I do the same procedure but using the corresponding UUID (00000003-0000-1000-   8000-00805f9b34fb) but by clicking on the checkbox to activate it tells me :

               

            java.lang.NullPointerException : Attempt to invoke virtual method ' int android.bluetooth.BluetoothGattCharacteristic.getProperties () ' on a null object reference

               


            I'm really lost and not to do more . Thank you

                      Jesús please post your program. Also have you checked the function using the dongle to see what it is sending?

                Hi, 

                   

                 

                   

                I've tried that and no notifications are coming up for the CapSense / 2nd characteristic. Do I need to change something in main.c to also change the type of the field? 

                   

                 

                   

                (why does changing the field allow for two notifications to be sent?)

                  I fixed the problem - the code in my BLE C file did not allow for notifications to be sent for the CapSense data.
